Climate Data Agency
In this intervention, we engage with Karen Barad's agential‐realist concept of intra‐action to explore how knowledge about climate emerges from the intra‐active entanglements between climate scientists and nature through processes of data collection, representation and interpretation. By adopting Barad's new materialist perspective, we employ the concept of climate data agency to understand the role of climate data in shaping both scientific inqu…
Heat, humidity and health impacts
The global health burden associated with exposure to heat is a grave concern and is projected to further increase under climate change. While physiological studies have demonstrated the role of humidity alongside temperature in exacerbating heat stress for humans, epidemiological findings remain conflicted. Understanding the intricate relationships between heat, humidity, and health outcomes is crucial to inform adaptation and drive increased glo…
Disentangling the causes of the 1816 European year without a summer
The European summer of 1816 has often been referred to as a ‘year without a summer’ due to anomalously cold conditions and unusual wetness, which led to widespread famines and agricultural failures. The cause has often been assumed to be the eruption of Mount Tambora in April 1815, however this link has not, until now, been proven. Here we apply state-of-the-art event attribution methods to quantify the contribution by the eruption and random wea…
The early 20th century warming
The most pronounced warming in the historical global climate record prior to the recent warming occurred over the first half of the 20th century and is known as the Early Twentieth Century Warming (ETCW). Understanding this period and the subsequent slowdown of warming is key to disentangling the relationship between decadal variability and the response to human influences in the present and future climate. This review discusses the observed chan…
Climate data empathy
In the era of climate services, which provide globally complete data products in a ready‐to‐use form, the context of climate data is in danger of being neglected or forgotten. However, the historical and present‐day context imprinted on this climate data is important in its own right. The data depend on political, economic and technological factors, as we show with a range of data coverage maps. We term awareness of and sensitivity to this contex…
Simulating crop yield losses in Switzerland for historical and present Tambora climate scenarios
Severe climatic anomalies in summer 1816, partly due to the eruption of Tambora in April 1815, contributed to delayed growth and poor harvests of important crops in Central Europe. Coinciding with adverse socio-economic conditions, this event triggered the last subsistence crisis in the western World. Here, we model reductions in potential crop yields for 1816 and 1817 and address the question, what impact a similar climatic anomaly would have to…
Tropical circulation and precipitation response to ozone depletion and recovery
Among the few well established changes in atmospheric circulation in recent decades are those caused by stratospheric ozone depletion. They include a strengthening and poleward contraction of the westerly atmospheric circulation over the Southern extratropics, i.e. a strengthening Southern Annular Mode (SAM), in austral spring and summer. Associated effects on extratropical temperature and precipitation and more recently subtropical precipitation…
Tambora 1815 as a test case for high impact volcanic eruptions
The eruption of Tambora (Indonesia) in April 1815 had substantial effects on global climate and led to the ‘Year Without a Summer’ of 1816 in Europe and North America. Although a tragic event—tens of thousands of people lost their lives—the eruption also was an ‘experiment of nature’ from which science has learned until today. The aim of this study is to summarize our current understanding of the Tambora eruption and its effects on climate as exp…
Arctic moisture source for Eurasian snow cover variations in autumn
Eurasian fall snow cover changes have been suggested as a driver for changes in the Arctic Oscillation and might provide a link between sea-ice decline in the Arctic during summer and atmospheric circulation in the following winter. However, the mechanism connecting snow cover in Eurasia to sea-ice decline in autumn is still under debate. Our analysis is based on snow observations from 820 Russian land stations, moisture transport using a Lagrang…
Climate change in Switzerland
Climate change is clearly discernible in observed climate records in Switzerland. It impacts on natural systems, ecosystems, and economic sectors such as agriculture, tourism, and energy, and it affects Swiss livelihood in various ways. The observed and projected changes call for a response from the political system, which in Switzerland is characterized by federalism and direct democratic instruments. Swiss climate science embraces natural and s…
Lessons for Science from the "Year without a Summer" of 1816 What Does It Take for Science to Respond to Climatic Change
The Twentieth Century Reanalysis Project
The Twentieth Century Reanalysis (20CR) project is an international effort to produce a comprehensive global atmospheric circulation dataset spanning the twentieth century, assimilating only surface pressure reports and using observed monthly sea‐surface temperature and sea‐ice distributions as boundary conditions. It is chiefly motivated by a need to provide an observational dataset with quantified uncertainties for validations of climate model …
Zum Wassertransport in den Alpen während der frühen Neuzeit
During the early modern period, the transport of goods and passengers on ships and rafts was widespread not only in the lowlands, but also in the Alps.The waterway played an important role for transporting heavy loads. It was commonly used for regional trade and could also be part of the transalpine trafic. However, the ability of rivers to carry ships or rafts was not a "natural" one but was human-generated. In a changing economical, technical a…
